Latest Patents

Randy's latest patents include a multi-focus optical reader with masked or apodized lens. This invention provides a method and apparatus for reading bar codes or other images while reducing or eliminating the need for self-generated illumination. The image reader is designed as a handheld unit that features an efficient optical collection system, including an aperture with a high aspect ratio and/or multi-focal lenses. An optically transmissive spacer affixed to the front of the handheld unit allows for the collection of ambient light at close range. Additionally, a diffuser may be used to reflect ambient light from the handheld unit to enhance illumination. The device incorporates a masked CCD detector with rectangular pixels, which is coupled to an adaptive exposure circuit to prevent saturation at high illumination levels. A correlated double sampling circuit is also included, which rejects common mode noise and enables operation in lower light levels. This circuit connects to a signal processor that employs a derivative-based technique for edge detection, allowing a decoder to extract encoded information from the image.
